A multimedia patient simulation for teaching and assessing endodontic diagnosis.
Full Abstract
Teaching and assessing diagnostic skills are difficult due to relatively small numbers of total clinical experiences and a shortage of clinical faculty. Patient simulations could help teach and assess diagnosis by displaying a well-defined diagnostic task, then providing informative feedback and opportunities for repetition and correction of errors. This report describes the development and initial evaluation of SimEndo I, a multimedia patient simulation program that could be used for teaching or assessing endodontic diagnosis. Students interact with a graphical interface that has four pull-down menus and related submenus. In response to student requests, the program presents patient information. Scoring is based on diagnosis of each case by endodontists. Pilot testing with seventy-four junior dental students identified numerous needed improvements to the user interface program. A multi-school field test of the interface program using three patient cases addressed three research questions:
1) How did the field test students evaluate SimEndo I? Overall mean evaluation was 8.1 on a 0 to 10 scale; 2) How many cases are needed to generate a reproducible diagnostic proficiency score for an individual student using the Rimoldi scoring procedure? Mean diagnostic proficiency scores by case ranged from .27 to .40 on a 0 to 1 scale; five cases would produce a score with a 0.80 reliability coefficient; and 3) Did students accurately diagnose each case? Mean correct diagnosis scores by case ranged from .54 to .78 on a 0 to 1 scale. We conclude that multimedia patient simulations offer a promising alternative for teaching and assessing student diagnostic skills.
